XPS Premium Insulation Boards are also used as a high quality insulation for our underwood heating systems, these boards are available in 6mm and 10mm thickness.
High compressive strength (30tonnes / m2), light weight, high efficiency and low cost make this thermal board an ideal choice when fitting heating on to a poorly insulated concrete or screed base.
If using with the underwood heating aluminium foil system they can be simply laid onto the surface in a staggered pattern.
For undertile systems this product must be fixed down using our flexible tile adhesive
